As you can see my sig, i ordered the test pipes with resonators. i heard toykillas and didnt want the raspiness. i also have the Boral TD which just makes it sound a **** of a lot deper. Also i went with the JWT because an intake is gonna bring u minimal gains and i think by keeping the stock plastic tube you will conduct less heat. Another big factor was that the JWT was $100 and i couldnt justify paying atleast 200 for an intake. So really the intake will be a preference issue.
